The story is set in a high school which is also the boundary of human and youkai worlds.
During the day, the school is your typical school filled with humans. When the night falls, it changes completely as youkai is all over the place as ‘students’.
The heroine, Suzue Shizuka, is a descendant of a water spirit. She has good grades and really strong. So strong that if she won’t let it out she’ll have a fever. That’s why together with her friend Hisoka, they do pranks all over the school.
